[PATCH 0/2] iommu/vt-d: Fix issues on probe error path

Posted by Pranjal Shrivastava 1 week, 2 days ago

This series addresses two pre-existing issues in the Intel VT-d driver's
probe error path. These issues were identified by Sashiko during the
review of the ATS series [1].

The first patch fixes an RB-tree corruption that occurs when probing
non-ATS devices. The second patch fixes a UAF by ensuring the per-device
private data pointer is cleared before freeing memory on failure.

Thanks,
